TU alltwhom it may concern f Beit known that I, WILLIAM A. E. HEN- Rior, a citizen of theUnited States, residing at Boston, county of Suffolk, andl State of Massachusetts, have invented an Improvement in Reversing Mechanism, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts. Y

This invention relates to a driving mechanism, which is adapted to automatically reverse the direction of rotation of the driven element at stated or predetermined times.

The device .has been especially designed for use in connection with a washing machine for rotating the drum thereof first in one direction and then .ih the other, but it will be obvious that the invention is not limited to use in connection with a washing machine but may be used in connection with any device where it is desired to provide for reversing automatically the direction of rotation of the driven element at stated periods of time.

Figure 1 :is a vertical' sectional view of the driving mechanism on substantially the line a-a, Fig. 2; Fig. 2 is a horizontal sectional view on substantially the line b-b, Fig. 1, said figure showing the casing for the gearing broken out to better show the construction; Fig. 3 is a horizontal section through the shaft supporting the clutches; Fig. 4 is an end view of the casing supporting the .driving mechanism, the driving shaft being shown in section; Fig. 5 is a detail of the clutchreversing mechanism; Fig.V 6 is a fragmentary view showing the bolt carriers in plan; Fig. 7 is a sectional view through one of the bolt carriers and the bolt operated thereby, said view also showing the clutchu operating yokes; Fig. 8 is a section on substantially the line cc, Fig. 9 looking downwardly; Fig. 9 is a side view of the reversing mechanism; Fig. 1() is a detail of the reversing mechanism; F ig. 11 is a bottom plan view of the frame sustaining the bolt`;car riers showing the mechanism for operating the bolts; Fig. 12 is a detail of the bolt carriers showing the locking device therefor.

The invention is herein embodied .in a device involving a driving shaft to which a driving pulley is secured and a separate 'driven shaft which .is geared to and 0 crates the mechanism or other part to be riven.

Each shaft has mounted thereon a clutchy and the two shafts and the clutch members thereon are so connected together that when one clutch is in engagement the driven shaft will be driven in one direction while when the other clutch is in engagement the driven shaft will be driven in the opposite direction. Referring now to the drawings and especially to Figs. 1, 2 and 3, the driving shaft is shown at 3 and it is adapted to be operated by a driving pulley 4 which is arranged to be clutched to thedriving shaft or unclutched therefrom by means .of a suitable vclutch 5. `The driven shaft is shown at 6 and it may be geared or connected to the device to be operated in any suitable manner according to the character of said ,devices l In the embodiment of the invention which I have herein selected for illustrating my invention, said driven shaft has thereon a worm 7 which meshes with and drives a wormy gear 8 that is sustained on a shaft 9. Where the device is used in connection with a washing machine, this shaft 9 may be that which carries the drum of the washing machine, but I` wish it distinctly understood that the character of the mechanism orv machine with which my invention is used has nothing to do.

thrust, and to enable the shaft 6 to carry this load with as little friction as possible I have provided, see Fig. 3, novel bearings for said shaft which are shown as comprising hardened shaft disks 6, having each a con- "ex face 6" and flat opposed face 6c provided with a rib 6d which may be received by a similarly shaped slot in each end of the shaft 6. The provision of these hardened disks obviates the necessity on the one hand of hardening the whole shaft after it is turned, which would be likely to warp it, and on the other hand it obviates the necessity of turning the shaft from the material which has been 'previously suitably hardened to the extent required, the latter course beingI both ditlicult and expensive. Similarly formed diskse are positioned one at either end of the shaft in the case 10, and between said disks and the disks 6a are positioned, one at each end, disks 6i, each having two convex faces 6g so that the shaft 6 is thereby provided with particularly eilicient bearings.

The driving pulley 4 is shown as mounted on a sleeve 12 Which surrounds the driving shaft 3, and the clutch 5 for clutching said sleeve to the driving shaft is inclosed with in the gear casing 10, 11.V r1`he clutch 5 may have any suitable or usual construction but preferably l will employ a clutch of the character shown either in my Patent No. 840,847, dated January 8, 1907, or in my copending application Se. No. 412,534, tiled January 25, 1908. Both of theseclutches are of that type which includes a friction coil which surrounds a drum and which is adapted to be tightened about the drum when the clutch is in operative engagement. Since the clutch forms no part of my pres ent invention 1 have not deemed it necessary to illustrate the clutch indetail.

ln Figs. 1 and 3 the clutch is shown sufficiently for the purposes of this application. 1t comprises the drum 13 which is rigid with the sleeve 12 and which is surrounded by.

the friction coil 14 which is carried by and is rotatable with a shell 16 which is fast on the shaft 3. Said coil 14 is tightened about the drum by means of a sliding actuator, not shown, which is operated by moving the clutch-actuating sleeve 15 longitudinally of the shaft. This clutch-actuating sleeve 15 is shown as supported byl the shell 16, and said sleeve is given its movementby means of a yoked lever 17 which is pivoted to the gear casing 10 at 18 and which 'is operated by a lever-'19 situated exterior to the gear casing and pivoted thereto at 21, said lever being connected to the yokedv lever 17l byA means of the link or connection 20. The movement of the clutch-actuating sleeve 15 to the right Figs. 1 and 3 throgws the clutch into engagement and its movement to the left disengages the clutch. A clutch having this construction is more completely described in my said patent and application to vwhich reference may be had. The lever 17 is provided, see Fig. 1, and herein near its upper end, with an aperture 17 a to receive one end of the brake rod 17 b which actuates the brake on the driven shaft 6 and will be subsequently further described.

The shell 16 has rigid therewith the gear meaeeo 4shaft 6. The clutch 5a on the driving shaft 6 is thrown into operative engagement orl disengaged by movement of the clutch-actuating sleeve 28 which surrounds the shell. The driving shaft 3 also has fast thereon the drum 29 of another clutch 5b (which is similar in construction to the clutch 5), said drum preferably being rigid with the gear 23. rllhis drum is surrounded by a friction coil 30 which is received within the shell or barrel 31, and said coil 30 is tightened about its drum by movement of the clutch-actuat ing sleeve 32 which surrounds the shell 31. rlChe shell or barrel 31 is loose upon the driving shaft 3 and has rigid therewith a gear 33 which meshes with and drives an idler 34, see Figs. 1 and 4, which idler meshes with and drives a gear 35 fast on the driven shaft .6. With such an arrangement of gearing and clutches it will be see-n that when the clutch on the shaft 3 isengaged and the clutch on the shaft 6 is disengaged, as illustrated in Fig. 3, then the gear 33 will be clutched to 'said shaft 3, while the gear 24 will be unclutched from the shaft 6. lVhen the driving shaft 3 lis rotated therefore the gear 33 Will'be rotated with said shaft and said gear will rotate the ydriven shaft 6 through the intermediate gear 34. `When the clutches are set in this manner, the shaft Y 6 will rotate in the same direction as the shaft 3, and during such rotation the gear 24 will turn loosely on said driven shaft 6. lf, on the other'hand, the clutches are re versed, that is, the clutch on the shaft 3 is disengaged while the clutcho-n the shaft 6 is engaged, then the gearr33 will be loose on the shaft 3, while the gear 24 is clutched to the shaft 6. rlhe rotation of the shaft 3 will, therefore, rotate the gear 23 Whichis fast thereon, and said gear will rotate the gear 24 which is clutched to the shaft 6, in which case the shaft 6 is rotated in an opposite direction to that in which the shaft 3 is rotated. Under these latter conditions, the gear 33 merely runs loosely on the shaft- 3, this being permitted because the clutch on said shaft is disengaged.

llt Will thus be seen that when the clutch on the shaft 3 is engaged and that on the shaft 6 is disengaged, the driven shaftis rotated in the same direction as that o f the driving shaft, while when the clutch on the drivin the driven shaft 6 is engaged, lsaid driven shaft will be rotated in an opposite direction from that of the drivin shaft.

lin order that the driven shaft 6 and the vll() shaft 3 is disengaged and that on a machine operated thereby may be stopped quickly when the pulley clutch 5 is unlocked from the shaft 3, I- have provided a brake for said shaft. here shown as a spring member 35a coiled about the shaft and adapted to be automatically tightened thereabout by means of the brake rod 17", see Fig. 1, actuated in turn by movement of the lever 17, to unlock the clutch 5 from the shaft 3. On the other hand, the reverse movement of the lever 17 to lock the clutch 5 to the shaft 3 will automatically unlock the brake 35 from the shaft 6.

The clutch-actuating sleeves 32 and 2S are given their movement by means of two clutch actuators 36, 37, seeFigs. 1 and 7, these clutch actuators being herein shown in the form of yokes which embrace the clutchactuating sleeves and are received in annular grooves therein. -These clutch actuators are slidably mounted on rods or supports 38 and 39, see Figs. 2 and 7.

My' invention includes a mechanism oy which theclutch actuators 36 and 37 may be automatically operated thereby to reverse the direction of rotation of the driven shaft. The invention also includes a mechanism by which the time of reversing of the driven shaft 6 may be adjusted.

For operating the clutch actuators 36, 37, I have provided the following mechanism: The clutch actuator 36 is provided with a nose or projection 40 and the clutch actuator 37 is provided with a similar nose or projection 41, see Fig. 5. noses 40 and 41 is a slide 42 provided with two transverse rooves in one of which is received a clutc i-engaging bolt 43, and in the other of which is received a clutch-disengaging bolt 44. These bolts are of a length equal to the width of the slide, as plainly indicated in Figs. 5 and 7, so that when they are `in their central position, as shown by the position of the bolt 43, Fig. 5, the movement of the slide will not operate the clutch actuators 36, 37. If, however, the bolt 44 is thrown out into the position shown in Fig. 5, then the movement of the slide 42 to the right in said figure will carry said bolt against the nose 40 and shift the clutch actuator 36 thereby to disengage the clutch 5b on the driving shaft 3. If when the slide 42 reaches the limit of its movement to the right and the bolt 43 is carried beyond the nose 41, said bolt 43 is moved toward the clutch actuator 37, then duringr the return movement of the slide the projecting end ot the bolt will engage the nose 41 and shift the clutch actuator 37 to the left Fig. 5, thereby throwing the clutch 5 on the driven shaft 6 into engagement. For disengagine,r the clutch 5* the clutch-disengaging bolt 44 is moved oppositely from what is shown in Fig. 5, so that during the movement of the Situated between the lbetween said pairs of be moved to the right Fig. 5, and for engaging the clutch 5" on the driving shaft 3, the clutch-engaging bolt 43 is moved toward the clutch actuator 36 when the slide is at the right-hand limit of its movement, so that when the slide moves toward the left Fig. 5, the clutch actuator I36 will be moved into the position shown in Fig. 5.

The slide 42 is supported in ways 45 formed in the gear casinglO, and said slide is held in its operative position by means of a cap plate or frame 46 which is sustained above the slide by the gear casing 10. The

slide is preferably operated from the driving shaft 3, and for this purpose said shaft is shown as having a worm 47 thereon which meshes with andfdrives a worm gear 48 on a vertically-extending shaft 49. Said shaft is connected to and drives a gear 5() and-said gear operates through other gears of the ireversing mechanism which will be hereinafter described to drive a gear 51 which is fast on a shaft 52 that is journaled in the cap plate or frame 46, said shaft 52 having at its lower end a crank pin 53 which is receive'd in a block 54 that slides back and forth in a groove 55 formed in the slide 42. The rotation of the shaft 52, therefore, oper ates to give the slide its reciprocating movement.

The bolts 43 and 44 are operated directly by bolt carriers 56 and 57. These bolt car riers are slidably mounted in the frame 46 for movement transversely of the slide. each bolt carrier being formed with the ribs 58 which are'received in ways in the frame 46. Each bolt carrier'is also provided on its under side with a rib 59 which is received in a groove 590 formed in the corresponding bolt, said ribs operating to lock the bolts to the bolt carriers, so that movement of the bolt carriers transversely of the slide will operate to shift the bolts in the slide. It will be noted that the bolts move back and forth with the slide, but this ribbed connection between the bolt carriers and the bolts permits this movement of the bolts while maintaining operative connections between the bolts and the bolt carriers. The bolt carriers are operated for shifting the bolts by .means of a rocker member 60,'see Figs. l, 2, 6, 8 and 11,\vhich is carried `by the stud 61 mounted in the frame 46, the extremities of the arms of the rocker being received in apertures formed in the bolt carriers. Each bolt carrier sustains a pair of spring-pressed pins 113 each acted on by a spring 112 which tends to move the pin toward the center of the bolt carrier. The ends of the arms of the rocker are received ins and the latter and their springs furnis i a yielding connection between the rocker and the bolt carriers, the purpose of which will be explained slide to the right theclutch actuator 37 will i more fully hereinafter.

The rocker 60 is operated first in one direction and then in the other for shifting the clutches by a time mechanism which in turn is operated from the driving shaft 3. l/Vhile it is within my invention to employ time mechanisms of different characters, yet I find that herein illustrated and described to be a satisfactory one.

As herein shown the rocker '60 has rigid ltherewith an arm 62 which is geared to-an arm 63 rigid with a shaft 64 also supported in the frame 46. rlhe shaft 64 has fast thereon two arms 65 and 66 which are adapted to be actuated by cam surfaces 67 and 68, respectively, on a cam member 69. These cam surfaces have a spiral shape as plainly seen in Figs. 2 and 9, and the cam 69 is arranged both to rotate and to move longitudinally as it rotates whereby as said cam moves,..one or the other of the cam shoulders engages one or the other of the arms 66 or 65 and thereby rocks the shaft 64,

7` the rocking of the shaft obviously operating thus reversingy the direction of rotation of 5 the shaft 70 l have herein provided the folthe rocker 60 to shift the bolt carrier. For giving the cam 69 its two movements, l ha ve mounted it on a shaft 70 which is jour.- naled at its lower end in the frame 46vand which at its upper end has the screwthreaded portion 71 that screw-threads into a fixed nut 72. The screw-threaded engagement with the nut 72 obviously gives the shaft a movement longitudinally thereof as it is rotated. For rotating the shaft it has splined thereto a gear :73 which is journaled in bearings in the lframe 46, said'gear being confined in the bearings against movement. longitudinally of the shaft 70. The gear 73 meshes with and is driven by the gear 5l which is rigid with the shaft 53 above referred to. The gear 51 is preferably a mutilated gear, as plainly seen in Fig. 2, so that it will operate the gear 73 intermiti tently, the construction being such that the `rear 73 will make one complete rotation during each rotation of the gear 51, the complete rotation of the gear 73 occurring duringa partial rotation of the gear 51, and the `rear 73 remaininglat rest during vthe remaining portion `of the rotation of Said gear-51. j f

For securing the reversing movement 1t is necessary that the shaft 64 should rock first in one direction and then in the other and therefore'. mechanism is provided for rotatingftheshaft 70 firstin one direction and then inf`v the other, the rotation of the shaft 70 in.. lone direction obviously :moving it longitudinally upwardly, Fig. 9, thereby to bringthe cam shoulder 68 1nto engagement with v*the arm 66, and the movement in the opposite direction carrying said shaft downwardly thereby to bring the cam shoulder '37 into engagement with the arm 65. For

either of the gears 81 or 83.

lowing mechanism: The gear 50 which is connected to the shaft 49 is mounted on a stud 80 whichis journaled in the frame 46 and which carries at its upper end a 'gear 81. Said frame 46 also has journaled therein another stud 82 which has thereon two gears 83, 84. The gear 84 meshes constantly with the gear 50 but the gear 83 is situated at a lower level than the gear 81, as

plainly seen in Fig. 9, and does not mesh therewith. The gear 51 has connected therewith a reversing gear 85, said reversing gear being locked to the gear 5 1, so that theyy ro-- tate in unison but being shiftable vertically so that it may be brought into mesh with To permit of this movement of the gear 85, said gear 51 is shown as having two pins 87 rising.

therefrom, which pins play in apertures formed in the reversing gear 85, and said reversing gear has rigid therewith a stem 88 which is received in an aXial b'ore formed in the shaft or stud 53, as seen. in Fig. 1. When the reversing gear 85 is elevated, as shown in Fig. l, so that it meshes directly with the gear 81, then 'the rotation of the shaft 49 is communicated directly through the gear 50, stud 80 and gear 81' to the gear 85, from which it is communicated through the pins 87 to the gear 51 and from the latter to the gear 73 and shaft'70. lf, on the other hand, the reversing 'gear 85 is lowered to carry it out of mesh with the gear 81 and into `mesh with the gear 83, then the rot-ation of the. shaft 49 will be communicated through the gear 50 to the gears 83 and 84 and from the latter gear tothe reversing gear 85. These gears 84 andv 85 constitute intermediate gears, and when thereversing gear 85 is in mesh with the gear 81 the shaft 70 will be rotated in one direction, while when said gear is .in mesh with the gear 84. the shaft will be rotated in the opposite direction, as will be obvious.

For shifting the position of the reversing gear, l have provided mechanism which is controlled by the cam member 69 of the time mechanism. The gear 85 has rigid therewith a headed pin 90 which is embraced by the forked end of a lever 91, said lever being pivoted to the frame 46 at 92, see Figs. 2, 8 and 10, and having one end formed with gear teeth 93 which mesh with gear teeth formed on an elbow-lever 94 also pivoted'to the frame 46 at 95. One arm of the elbow-lever 94 is pivotally connected to a throw member 96 which ,is mounted to slide back and forth in bearings 97 formed in the frame 46. The mechanism for oper ating the throw member is such that the movement thereof at the proper time will be a quick movement. For this purpose the throw member is actuated' directly by a spring gradually by the turning movement of the which is put under compression lSC ' mss-,eco

shaft 64, and provision-'is made for releas ing thespring at the proper time to permit the throw member to loperate quickly. As herein shown, said throw member has surrounding the same a.' sleeve 98 having rigid therewith at each endcam` members 99. Situated between the sleeve 98 and the throw cmember is a coiled sprin 100 which is confined between the shoul ers 101 formed on said throw member and also between other shoulders 102` formed on the cam members 99. The space between the cam members 99 constitutes a groove in which is received the end` of a lever 103 that is rigid with the shaftv 64.

105 and 106 are two latches which are pivoted to the bearings 97 Y and which are connected by a spring 108. These latches are adapted to engage notches 110 and 111 in the throw member and are `for the purpose of normally holding the throw member 96'from movement. They are released at the proper times by the engagement of the cam members. 99 therewith. When the parts are in the position shown in Fig. 8, the latch 106 is in. lengagement with its notch 111'in t-he throw member, and said memberv is prevented from movement toward t-he left. As the shaft 64 turns to swing the arm 103 toward the left, the sleeve 98 with thecam members is moved on the throw member 96 and during such movement the springlOO will be compressed. When the sleeve has moved sufficiently toward the left to bring the cam member 99 into engagement with the latch 106 the latch is forced backwardly out of engagement with the notch 111 in the. throw memberand Athe resiliency of the spring 100 will then shift the throw member toward the left with a uick movement, such shifting movement o the throw member rocking the-'elbow lever 94 and through its connection with the lever 91 turning said latter lever to carry the gear 85 downwardly out of mesh with the gear 81 and into mesh with the gear 83, thus reversing the direction of movement of the shaft 70. When the throw member has been moved to the limit of its `movement to the left Fig. 1,'the latch 105 drops into engagement with thenotch y110 in said throw member, thus locking it from movement toward the right, and whengthe shaft 64 turns in a direction to swing the arm 103 to the Aright the sleeve is moved to depress the Ispring 100 and when the cam member99 on theV sleeve has released thel latch 105 the throwmember is shifted toward the right with a quick movement thereby reversing the position of the gear 85 and carrying it into the position shown in full lines Fig. 1 again.

To guard against dislocation of the cam shaft from its alinement, if for any reason the cam 69 should fail to actuate the reversing mechanism, asfor instance, if any foreign matter or member shouldv become so wedged between the gears as to prevent the throwing of the bolts 44, I have pro vided a cam shaft balancing means. .This balancing means, while permitting continued rotation of the cam shaft T0, under such circumstances as just referred to, will however retain the shaft in alinement and in position to again become operative as soon as the trouble has been remedied.

From the described construction of the cam shaft, it will be evident that if, for any reason, the shaft (S- is prevented from rocking to throw the bolts 44, the cam shaft 70 will continuo to rotate in one direction until the screw thread thereon runs out and becomes disengaged from the nut 72. In this case it' the shaft be traveling upwardly it will very likely become dislocated from its proper alinement. If, on the other hand, the shaft be traveling downwardly, it may drop when it becomes disengaged from the nut 72. In either of such cases it is mostdesirable to retain the shaft in alinement with the nut 7 2, so that the thread may engage the nut again when the machine has been reversed. To accomplish this result, I have drilled the upper end of the shaft 70 vertically and inserted therein a spring actuated plunger 72. This plunger is pro- 'vided with two collars T2" and "(2"l fast thereon and between said collars and Seated thereagainst is a coiled spring 72d. The plunger is retained in position in the shaft 70 by a thimble 72e threaded into the upper end of the shaft. If the reversing means failsto work and the'shaft 70 continues to travel upwardly, just as the shaft 70 becomes disengaged from the nut 72 the head 72 of the plunger 72 will strike the top of the dome 72K. see Fig. 1, and compress the spring 72d sutiicently to retain the shaft 70 in alinement with the nut `72 and ready to engage the saine again, permitting the shaft to rotate. freely in the meantime however. If'the shaft travels downwardly through the nut T2, the head 7 2f of the plunger will rest on the upper end of the nut and, while permitting the shaft 70 to rotate, the spring 72d will ac t to keep the shaft from dropping away from the nut and will retain it in alinement therewith ready to engage the same` when the mechanism has been reversed.

While the operation of the parts as thus far described will be a parent to thoseskilled in theart, yet a c carer comprehension of the invention may be had if thc operation is briefly described.

Assuming that the clutches are in the position shown in Fig. 3 with the clutch 5b on the driving shaft. 3 out of engagement and ythe clutch 5 on the driven shaft 6 engaged,

it will be observed that the two shafts will rotate in opposite directions and the clutch actuators 36, '37 will be in the positions shown in Fig. 5. When the clutches are in this position the gear 85 is in its lowered position meshing with the gear 83. rlhe rotation ofthe driving shaft 3 will through the gears 47 and 48 operate the driving shaft 49 in a direction to turn the gear 51 in the direction of the arrow Fig. 2. Said gear meshing with the gear 73 rotates it in the direction of the arrow Fig. 2 andfthis gear gives rotation to the gear 51, said latter gear giving an intermittent rotation to the gear 73 in a direction to screw the shaft 70 upwardly into the nut 72 in Fig. 9. As the mechanism continues to operate, the shaft 70 is screwed upwardly in the nut 72 until the cam shoulder 68 engages the arm 66. As said arm rides up the cam shoulder 68,

lthe shaft 64 is turned gradually and because of its geared connection with the rocker 60, said rocker is swung into the position shown in Fig. 8. The shifting of the rocker into this position will obviously throw the bolt carriers into the position shown in Figs. 6 and 8- provided the slideis so positioned that the bolts may be projected without engaging the noses 40 and 41. Assuming that the slide is in the position shown in Fig. 5, then such movement of the rocker will shift the bolt carrier 57 thereby to project the clutch-disengaging bolt 44 into the position shown in Fig. 5. The bolt carrier 56, how ever, is prevented from movement because the clutch-engaging bolt 43 is still in engagement with the nose 41, but the spring 11.2 in said bolt carrier permits the rocker to move, said spring being. compressed by the movement of the rocker. The movement of the slide 42 to the right Fig. 5 brings the projected clutch-disengaging bolt 44 into engagement with the nose 40, thus shifting the clutch actuator 36 and disengaging the clutch 5* on the driving shaft 3. When the slide 42 has moved to the limit of its movement to the right, the spring 112 comes into play to project the clutch-engaging bolt 43 so that when the `slide moves toward the left Fig. 5 it will engage the nose 41 and throw the clutch 5a on the driven shaft 6 `out of engagement, thus reversing the direction of rotation of the driven shaft.

The-swinging of the rocker 6() into the position shown in Fig. 8 operates to turn the arms 63 and 103` thereby moving the sleeve 98 on the throw member 96 and compressing the spring 100. When the sleeve has been moved suiiicientlyto release Athe latch 105 from the notch 110, `the spring 100 will shift the throw member into the position shown in Fig. 8 and in doing so will operate through the lever 91 to raise the gear 85 into its elevated position, thus carrying it out of mesh with the gear 83 and into mesh with the gear 81. This is the position of the parts shown in Figs. 1, 2, 8 and 9.

nosaeeo 'The shifting of the gear 85 operates to cause a reversing in the direction of movement of the shaft 70, and as the mechanism continues to operate in the reversed direction, the shaft 70 is screwed down out of the bolt 71 until the cam shoulder 67 engages the arm -when the shaft 64 -will be turned in a direction to project the clutch-engaging bolt 43 toward the clutch actuator 36 and to project the clutch-disengaging bolt 44 to-y ward the clutch actuator 37. When this result is accomplished the clutches will be reversed again" as ,above described, and at the same time the throw member will be shift.- edftoward the left Fig. 8 to again shift the position of the gear 85 and bring it into engagement with the gear 83.

The object in making the gear 74 mutilated yis so that the movement of the shaft will be comparatively quick,.that is, it will receive its entire movement at each step during a portion only of the complete rotation of the gear 74.

- The parts are so constructed that Vthe catches 106, 105 are not released until the lingers 65 and 66 have ridden up the cam ho-ulder to the periphery of the cam memier.

As 'described above the invention is adapted for automatically reversing the direction of movement of the driven shaft at stated periods of time. I have also provided forl securing this reversing at any desired periods, that is, after the driven shaft has made ten revolutions, or any other desired \r0\ number of revolutions. To accomplish this the arm 66 is adjustably mounted so that c it can be adjusted toward and from the arm 65. Said arm 66 is shown as carried by a sleeve 115 which is splined to the shaft 64 105 but which can be moved longitudinally of said shaft. To hold the sleeve in its adjusted position the latter is provided with notches 116 into one of which a sliding catch 117 may be-inserted, said catch being 11o supported by the bearing 118 at the upper end of the shaft and held in adjusted position by the screw 119. The sleeve .115 is provided at its upper end with a head 120 by which it may be raised and lowered after the catch 117. is removed.

My invention also comprehends a constructionby which the device may be madeA to run continuously in either direction, as

well as to reverse at stated intervals, as above described. Tok accomplish this result/1" means are provided for locking the bolt carriers in their central or neutral position. When the bolt carriers are thus locked, any movement ofthe rocker 60 will simply com- 125 press the springs 112, but will not shift the bolt carriers thereby to give movement to the clutch-engaging or. clutch-disengaging v bolts. For thus locking the boltcarriers in their neutral position 1 have provided the 130 more locking slide 130 which is arranged to move back and forth in ways 131 formed in the frame 46, see Fig. 11. This locking slide is arranged to b e actuated b a handle 132 which is secured thereto an which projects' therefrom upwardly through the top of the gear casing 10, as shown in Fig. 4, said handle playing in a slot 133 formed in 'the frame 46. This locking slide has secured thereto two pins or projections 134 and each bolt carrier has formed on its upper side a groove 135 adapted to receive one .of the pins. These grooves are provided with flaring mouths 136 see Figs. 6 and 11. Normally when the mechanism is in position to reverse the operation of the driven' shaft, the locking slide is-in the position shown in Figs. 6 and 11 with the pins 134 `standing' at one side of the bolt carriers. When it is desired to cause the driven shaft to rotate in one direction-only, the locking slide is moved toward the left Figs. 6 and/11 by the handle 132 until the pins 134 are received in the grooves 135 when said pins will lock the bolt carriers from movement. If the bolt carriers are not centrally situated at the time that the locking slide is moved, said slide operates to centralize them bythe engagement oflthe pins 134 with the walls of the flaring mouths 136. When the bolt carriers are unlocked so as to permit the mechanism to again reverse the direction of rotation of the driven shaft, it is essential that the bolt carrier 57 should be released first because-it is that bolt carrier which controls the clutch-disengaging bolt and it' is important that the clutch-disengaging bolt should be made operative to disengage the engaged clutch before the clutch-engaging bolt is made operative to engage the 'disengaged clutch, for otherwise the two clutches might be engaged at the same time, thus locking the mechanism. To prevent this from happening I have provided an auxiliary locking slide 140 which is mounted in the frame 46, as shown in Fig. 11, and which moves transversely of the bolt carriers. The end 141 of the slide 140 is wedge-shaped, see Figs.'11 and 12, and is adapted to engage a V-shaped notch 142m one of the ribs 58 of the bolt carrier 57. The slide is cut away in one side to receive the top of the bolt carrier 56 and one of the ribs 58 of said bolt carrier 56 is provided with a notch 143'adapted to receive the portion 144 of the slide. The locking slide 136 is vided with the arm 146 which is of a length to engage the end of the auxiliary slide 140. When the locking slide is moved into position to lock the bolt carriers, the arm 146 engages the slide 140 and moves the latter to the left Fig. 11 thereby carrying the beveled `end 141 into the V-shaped notch 142 and also carrying the portion .144 into the notch 1.43,. This slide 140, therefore, constitutes an auxiliary lock for the bolt carrier 56 for when pro--f Figs. 6 and 11, such movement does not un- 70 lock the bolt carrier 56, for the latter will remain locked by the auxiliary locking slide 140 until said slide is moved backwardly. When the locking slide 130 is moved into the position shown in Figs. 6 and 11, the bolt 75' carrier 57 becomes unlocked and it is free to move, but the bolt carrier 56 remains locked by the auxiliary slide 140, as above described. As lsoon as the bolt carrier 57 has moved in one direction or the other, the walls of the V-shaped notch 142 operate to move the auxiliary locking slide 140 to the right suiiiciently to unlock the bolt carrier 56. It will be seen, however, that in any case the holt carrier 57 must always be unlocked first and since this is the one which operates the clutch-disengaging bolt, it will follow that the engaged clutch must always be disengagel before the disengaging clutch is en gage i Having described my invention, what I claim as new and desire to secure by Letters Patent is `1.
